This study investigates the expression and function of neuropeptides and their receptors in the Colorado potato beetle (Leptinotarsa decemlineata), a major potato pest. Using RNA interference (RNAi) to knock down GPA2 and its receptor LGR1, the researchers demonstrated their roles in regulating developmental timing and life-stage transitions, providing insights for potential pest control strategies.
This paper presents the first chromosome-level genome assembly of the potato leafhopper (Empoasca fabae), a major insect pest that causes significant damage to potato crops. This genomic resource provides a foundation for understanding the pest's biology and developing targeted pest management strategies to protect potato cultivation.
This study describes the design and synthesis of Trolox derivatives with dual antioxidant and tyrosinase inhibitory properties. The lead compound, 5a, was demonstrated to effectively prevent enzymatic browning in fresh-cut potatoes by inhibiting tyrosinase activity through copper chelation, hydrogen bonding, and hydrophobic interactions.
This study identifies a molecular module consisting of StJAZ1-Like, StPIF02, and StPIN3 that regulates shoot and tuber apical dominance in potato. The findings elucidate the genetic mechanisms controlling branching and sprouting, which are key traits for potato cultivation and storage.
The study develops a genetically encoded chimeric protein degrader (AIM-REBT) that targets Phytophthora RXLR effectors for autophagic degradation. Stable expression of this degrader in potato plants confers robust resistance against Phytophthora pathogens without causing growth defects, offering a novel strategy for engineering disease resistance.
This study investigates the incorporation of a double emulsion containing annatto seed extract into potato starch-based films to develop active biodegradable packaging. The resulting films exhibited significantly improved moisture resistance, water vapor permeability, UV-vis barrier properties, and antioxidant activity while maintaining structural integrity.
This study examines the preparation of starch-phenolic acid complexes using potato, corn, and pea starches to understand how the botanical source influences their structure and digestibility. The research demonstrates that the starch source and phenolic acid type synergistically affect the complex architecture and enzymatic resistance. These findings contribute to the development of potato-derived digestion-resistant food ingredients.
This study investigates how starch granules from potato, maize, and wheat affect disulfide bond formation in urea-solubilized glutenin (USG) within wheat-based dough systems. The findings reveal that potato starch granules interact with USG through hydrogen bonding and physical entanglement, altering the protein's conformation and disulfide bond content. This research provides a mechanistic basis for optimizing the quality of cereal-based food products supplemented with potato starch.
This study analyzes the N-glycosylation profiles of patatin, the major storage protein in potato tubers, across three different cultivars using mass spectrometry. The researchers identified cultivar-specific variations in N-glycan structures and abundances, including two novel glycan structures. These findings provide valuable glycomic data to support potato germplasm screening and the functional modification of potato proteins.
This study investigates the molecular, chemical, and microstructural properties of starch-polyphenol complexes using starches from wheat, rice, potato, and maize. The findings reveal that polyphenols, particularly epigallocatechin gallate and quercetin, alter starch molecular organization and morphology through hydrogen bonding. These insights support the development of potato-derived and other starch-based functional foods with enhanced nutritional properties.
